It might be impossible to configure other attributes (e.g.: events, scale, sampling rate) if they impact the currently active buffer capture session. On ADXL367, writing to register before 0x2E requires the device to be placed in standby mode, otherwise the changes might be effective for only part of a measurement. To ensure this requirement, the configuration attributes of the IIO device try to claim direct mode before switching to standby mode. During a buffer capture, direct mode cannot be claimed, and the attribute write callback returns -EBUSY. Describe this behavior in the buffer/enable attribute description.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
